Description by ryoichi yamamoto Written by the developer, not by AppBrain. Click to read.
ヘリコプターの燃料と飛行時間を、その場で計算するための道具です。

給油伝票はkg、タンクの容量はL、マニュアルはlb。現場では単位がばらばらで、そのたびに換算しなおすことになります。Fuel はその手間をなくすために作りました。

■ 4つの計算

・時間計算 — 残燃料から、あと何時間何分飛べるか。予備に残す量と、すでに飛んだ時間を差し引けます
・燃料計算 — 飛行時間から、必要な燃料の量
・燃費計算 — 実際に飛んだ時間と使った燃料から、1時間あたりの消費率
・単位換算 — キロ・ポンド・リットル・ガロンを相互に

■ 機体を登録しておける

機体ごとの燃料消費率を登録すると、以降は機体を選ぶだけで呼び出せます。実際に飛んだ実績から出した消費率を、そのまま登録することもできます。

■ 重量と容積は密度でつなぐ

Jet A-1(0.80 kg/L)、AVGAS 100LL(0.72 kg/L)に加え、給油伝票の実測値も入れられます。Jet A-1 の密度は温度で 0.775〜0.840 kg/L の幅があるため、厳密に出したいときは実測値をお使いください。

■ 読めない入力は計算しません

「1:75」のような有り得ない時刻や、数字でない文字を入れたときは、勝手に別の数字として解釈せず、計算結果を出しません。静かに間違った答えを返さないことを、この種の道具でいちばん大事な性質だと考えています。

■ 通信しません

入力した内容は端末の中だけに保存され、外部へ送信されません。圏外でも機内でも同じように動きます。アカウント登録も不要です。

■ ご利用にあたって

ここで出る数値は巡航時のならしを前提とした目安です。ホバリング・上昇・外気温・搭載状態によって実際の燃料消費は変わります。搭載燃料の可否判断や飛行中の残存時間の判断には、必ず当該機のフライトマニュアルと計器の指示を優先してください。本アプリは運航上の判断を代替するものではありません。

■ 料金について

4つの計算はすべて無料で使えます。機体の登録は1機まで無料で、2機目以降は買い切りでご購入いただけます。
